Detailed Description Of The Invention
As shown in Figure 1, punch 1 of the present invention comprises a punch framework 2 that has perforated base 3, and pedestal has a paper matrix outlet perforate 4.The punch framework also comprises a horizontal punch frame parts 5 and paper thickness limits parts 6.In these parts each all comprises the perforate 7,8 of a perforation guiding respectively, is used to install pecker 9, and its y direction along pecker is moved.Guiding perforate 7 and 8 is axially aligned along the y direction and the paper matrix outlet perforate 4 of pecker 9, and the lengthwise movement of pecker downward direction will cause pecker to be moved into paper delivery perforate 4.
The pecker driver part 10 that moves through of pecker is realized, uses the driver part of pivotal mounting to rotate around point 11.By applying a power F of pressing to driver part elongated end 11, can realize the pivoting action of driver part downward direction.Drive surfaces 12 engaged with first upper end 13 of pecker 9 in the middle of this will cause, and it is moved down.
As shown in figs. 1 and 4, paper thickness limits parts 6 are positioned on the perforated base 3, and it is the pile opening of SH that interval between the two defines heap thickness, and SH measures along the pecker y direction.This heap thickness SH equals the maximum ga(u)ge of multipage pile S, and pile S will get a hole by pecker 9.
As shown in figs. 1 and 4, second lower end 14 of pecker 9 will be passed through until bottom page BS from top page TS, and enter in the perforate 4 of base component 3, thereby pass pile S in moving downward process.In practice, punch generally comprises two or more peckers, to get two or more holes in pile.For purpose clearly, only shown a pecker in the accompanying drawings.
According to technology of the present invention, the shape of the lower end 14 of processing pecker is to limit single inverted V-type groove 15.This groove comprises the termination endface 16 that is positioned on the pecker diameter facing surfaces, and it becomes the plane to extend perpendicular to the pecker y direction.The cross section of pecker main part is columniform, and its 14 places, lower end are so at least.V-type groove 15 comprises side plane surface 17 and the top-surface camber 18 that is connected these two side surfaces 17.Have the side surface of periphery and the cutting edge 19 (Fig. 3) that curved surface has formed pecker together.
In making a call to a process by the hole of maximum ga(u)ge pile, for reducing the needed maximum, force of operation punch, the structure of having found the pecker lower end is very crucial.The most important thing is that the height GH of V-type groove 15 need be greater than the height SH of heap opening, pile S can insert this heap opening so that perforation.Simultaneously, the wrapping angle V between the radius R of 18 machining shapes of curved surface and the V-type groove side surface 17 also is very important.
In following Table A, three different punch model groove height and the ratio of pile height SH and other sizes of pecker have been provided.It has provided the information of the new model of the former prior art model and the corresponding transformation of the way according to the invention.In addition, Table A has shown master mould and the required average peak-peak power of new model of the present invention realization perforation procedure.

Can easily find out from the curve of Fig. 5-7 and Table A, B: the peak-peak power of new model is significantly less than the corresponding old model of prior art.Shown in the bottom of Table A, improvement of the present invention causes peak-peak power to reduce by 27% to 59%.The reduction of this peak-peak power not only makes the operator realize that by hand perforation procedure becomes easier, and because suffered less this fact of power of material, can allow uses cheap materials makes punch.
Fig. 8,9 and 10 has shown all places of pecker in mobile perforation procedure.First and the rearmost position represent the initial sum completing place of pecker, and second the pecker position when running into different peak force A and B with the representative of the 3rd position.
Specifically, Fig. 8 has shown the pecker position of the old prior art of model I and II, wherein only runs into single peak-peak power A.On the other hand, Fig. 9 has shown the pecker position of the prior art of model III, has wherein also run into second peak force C.At last, Figure 10 has shown the pecker position by the technology of the present invention manufacturing of model I, II and III.
After measured, in the cutting operation that pecker produces during by pile, always strict cutting edge and the shearing manipulation between the mould perforate as pecker of cutting takes place.In paper perforation, enter pile and bored a hole in the paper extruding of alignment, the center that bend into pecker by pecker.Move through pile and arrive maximum at pecker, be i.e. during top page TS contact V-type groove top-surface camber, further push.If there are not enough spaces to hold paper in pecker, paper will highly be compressed, and peak-peak power is corresponding to uprise and this can cause.In some cases, this can cause pecker to quit work.
For the prior art structure of pecker, wherein undesirable pile height extruding because there is not the clearance spaces of sufficient amount to hold perforated paper, will take place less than the height that is perforated pile in the height of V-type groove.Shown in second position of prior art pecker in Fig. 8 and 9, peak-peak power corresponding to the position of pecker is: the curved surface of V-type groove 18 ' the contact pile top page (Fig. 8) or very near the top page (Fig. 9).The terminal surface 16 ' of pecker still is positioned at the inside of pile S at this moment, on the page BS of top suitable distance is arranged.
On the contrary, when arriving peak-peak power, pecker of the present invention still provides sizable space between top page TS and V-type groove upper surface 18.Simultaneously, the almost whole body of wearing pile S of cutting of the terminal surface 16 of pecker is downwards until bottom page BS.Therefore, the height that runs into of prior art structure is squeezed in the structure of the present invention and will can run into.This causes conversely realizing that the required maximum, force of perforation procedure has reduced.
In addition, for pecker of the present invention, run into second peak load in different pecker positions with model III prior art structure.Figure 10 has shown general when the top-surface camber 18 of V-type groove during with the pile top page TS horizontal alignment that is positioned under the pecker, and second peak force takes place.This at present terminal surface 16 passed the bottom page BS of pile.For the model III prior art structure that runs into second peak force, when terminal surface 16 ' is positioned at pile S inside by pile bottom page BS and top-surface camber 18 ' just, will run into this power.
Should illustrate at last: the pecker elongation numerical value during C row and D are listed as among the table B comprises an increment, and it is the perpendicular separation of pecker on pile during corresponding to the starting position, shown in Fig. 8,9 and 10 left side.Equally, position about prior art pecker shown in Figure 8, do not have second peak force because having only a peak-peak power, among Fig. 8 from the pecker position shown in the 3rd figure in a left side, corresponding to the pecker that moves down along the slope of curve that is shown in Fig. 5 a, 5c, 6a, 6b and 6c.As for second peak force that is shown among Fig. 5 b, be sure of to produce this peak value when following terminal surface 16 ' at pecker passes the bottom page BS of pile.Therefore, this position display of pecker is in Fig. 8.
